Forest genetics research at the Forestry and Game Management Research Institute in Strnady has focused on long-term research evaluation of the performance of forest tree species. One of the important tree species we have studied is silver fir (Abies alba Mill.). In order to better understand the challenges in regeneration and stand development of silver fir stands, 20 provenance research plots were established in the former Czechoslovakia between 1973 and 1977. In this paper, we present the results of the evaluation of silver fir in provenance plots 73 and 79, containing 36-year-old trees established in the spring of 1977 on the Training Forest District Hůrky near Písek (Southern Bohemia). Research plot 73 contains a total of 16 provenances of origin from the Czech Republic, Slovak Republic, Romania, Italy, Austria, Germany and Hungary. Research plot 79 contains 20 provenances from the Czech Republic, Germany, Austria, Hungary and Bulgaria. Over time, the total height and DBH were measured and the mean stem volume and mean stem growing stock per hectare were calculated. Based on our analysis of mean height and diameter growth and total volume production, we concluded that the superior provenances were two Austrian provenances (A 95 – Gröbming and A 96 – Thal-Wechselgebiet) and two Czech provenances (CZ 88 – VLS Hořovice and CZ 130 – Nasavrky). The lowest performing provenances were two Austrian provenances (A 93 – Wörschachwald and A 94 – Schneegattern) and one Czech provenance (CZ 51 – Lipník nad Bečvou).
